Segmentation fault enabling profiling

[Tron Thomas]

I have an application that is running slow, so I wanted to profile it to 
see if I could tell where the bottle neck exists in the code.

I enabled profiling by using the -pg switch both while compiling and 
linking.

Now when I run the program I get a segmentation fault without any core 
dump.  Also, if I run the program in the debugger, the debugger is 
unable to provide any kind of backtrace when the fault occurs.

If I remove the -pg switch, my application builds and runs without crashing.

Does anyone have any suggestions?
